This invention relates to a device for drying razor blades, which consists of a piece of cardboard or similar stiff material folded to form a sleeve or envelope for example in box shape containing sheets of blotting paper or other absorbing material forming the drying inserts. An embodiment of the invention is illus- "trated by way of example on the accompanying drawings in which:

a Fig. l is a perspective view of the drying device in closed condition without razor blades.

Fig. 2 is a similar view showing the device open with the last inserted razor blade on top. I

Fig. 8 shows the device in top plan view, the closing flap open and fresh blades in the envelope.

Figure 4c is a longitudinal sectional view of the device;

Figure 5 is a side edge elevational view of another form of device in closed condition; Figure 6 is a schematic view showing how the device is opened; and

Figure 7 is a view similar to Figure 6 showing the inaccessible positioning of the used blades.

The novelty of the invention consists in 3 the advantages which will be hereinafter enumerated and by which the device according to the invention differs owing to its pcculiar construction from the drying devices for razor blades of known type.

blade a, which has just been used and for storing this blade for repeated use, and for collecting the worn blades 6, but it comprises a separate compartment 0, (Z for new, un-

used blades.

Fig. 4. shows by way of example a construction according to which the separate compartment 0 is formed in that the hollow space in the envelope 6 in such of dimensions that between the drying sheets f and the The device serves not only for drying the back wall 9 of the envelope 6 a sufficiently large space is left to accommodate several, for instance 2, 5, 10 fresh blades p which may be wrapped or not.

Fig. 5 shows anotherform of construction in which the separate compartment (2 is on the outer side of the envelope 6.

It is not necessary to search for the razor blade a which has been used recently if this blade has to be used again, as when a finger is slipped over the edges of the drying sheets 7 (Fig. 6), they open automatically at the point where this last used blade a is stored, the other blades 6 being secured (Fig. 7 so that they can no longer be gripped or reso moved even accidentally. To remove these worn blades 6 the last inserted blade a has first to be removed, whereupon the blades b can be successively removed one by one.

The positive opening of the drying sheets at the blade which has been last inserted and is lying on top is due to the fact that the front wall of the envelope 6 is adapted to be turned over up to a break it and which is situated lower than the upper edges of the inserted blades which, as they project into the stationary portion 2' of the envelope, cannot be bent downwards with the lid and the empty sheets 70 between the same, but remain stationary.

Independently of the number of blades inserted the drying sheets f are held together permanently with the same pressure (Figs. 1 and 4:), owing to two folding flaps Z on the longitudinal edges of the front wall, which by their spring power press the closed flap m as cover against the sheets f, becoming however inoperative as soon as the flap is opened so that the blades are liberated and can be removed.

The box when not "in use is closed by the extended rear flap being pushed as tongue n into the resilient longitudinal fold Z (Figs. 1 and 5), a closure which keeps the drying sheets depressed on their whole Width and which, notwithstanding its simple construction, can never fail nor automatically open nor be opened accidentally by the pressure exerted by the inserts, so that it is superior to other closing means such as spring buttons and the like.

Damaging of the blades or of the cutting edges of the blades at the inserting into the drying device or during the drying is impossible, even at careless handling, as the blade is inserted or removed only when lying flat and dried at the state of rest and not by moving to and fro; and specially therefore that no fixation means, such as metal clamps or the like, traverse the drying sheets, and that these sheets are not held together by glue or any other adhesive, but are lying loosely in the envelope (Fig. 3), whereby their movability and adaptability to the number of blades inserted are obtained.

1 claim:

1. A device for drying and storing razor blades, comprising a back portion folded over at one end to form a pocket extending over a portion of the entire length of the device and a pack of sheets of absorbent material in said pocket adapted to receive razor blades and to be bent over the front edge of said WALTER H. LoWENsTEIN.

pocket to always expose the uppermost blade inserted in said pack.

2. A device as specified in claim 1, com prising in combination with the back portion folded over to form a pocket and the pack of absorbent sheets, a front sheet of stiff material on said pack having a break corresponding with the edge of the front portion of the back folded over to form the pocket and adapted to be bent over with the sheets of the pack to always expose the uppermost blade inserted in said pack.

3. A device as specified in claim 1, comprising in combination with the back portion folded over to form a pocket and the pack of absorbent sheets, an extension on the opposite end of said back portion to that forming the pocket adapted to bent over said pack and engage under the edge of the pocket to protect the front of said pack and prevent the inserted razor blades from falling out of said pack.

4. A device as specified in claim 1, comprising in combination with the back portion folded over to form a pocket and the pack of absorbent sheets, a front sheet inserted in said pocket over said pack, and resilient folded over flaps one on each longitudinal edge of said insert front sheet adapted to compress said pack of absorbent sheets and secure the pack in said pocket independently of the number of blades inserted between the sheets of said pack.
